Flammschutzmittel: Rondol Extruder in Forschungsprojekt in Ankara University23 Okt 2011
The Rondol 10mm Twin Screw Extruder proved to be a useful tool to improve the flame retardant properties of High Impact Polystyrene (HIPS) and to further reduce its production cost. HIPS is widely used for housings of electric and electronic equipments from TV sets to refrigerators. The flame retardancy is achieved by an expensive combination of brominated additives and antimony oxide. Scientists at the Middle East Technical University, Ankara, discovered a way to replace half of the antimony oxide, by the bromine free Colemanite.
